hii've got a simple question. i' ve got a message driven bean who listen to a queue. is it possible that a message driven bean can listen to several queues and topics or is it defition that a message driven bean can only listen to one queue or topic.thanks

Theoretical it would probably be possible, but its not in JBoss, but all you need to do to get the "same" bean to listen to multiple queues it to deploy it more times with different config (new jar name, new bean name, new destination).
